Procedure
Copied from the source record, unedited
2-methoxy-4-morpholinoaniline (158 mg, 0.76 mmol), 2-(2,5-dichloropyridin-4-ylamino)-N-methylbenzamide (150 mg, 0.51 mmol),diacetoxypalladium (5.69 mg, 0.03 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (29.3 mg, 0.05 mmol) and cesium carbonate (330 mg, 1.01 mmol) were weighed out in a microwave vial and sealed. dioxane (3 mL) was added and argon was let to bubble for 5 minutes at rt. The resulting mixture was stirred at 110 °C for 1 hour. The reaction mixture was allowed to cool to room temperature and concentrated in presence of decalite speed plus. The crude product was purified by flash chromatography on silica gel eluting with 0 to 4% methanol in ethyl acetate/DCM (1/1). The solvent was evaporated to dryness. The foam was triturated in terbutyl methyl ether and the

How to read this record
This is one experiment, not a rule. It says that on one occasion these species were combined under these conditions and this came out. It does not say the reaction will give the same result on your substrate, and nothing on the page has been generalised into a claim that it would.
The pathway is a separate question, kept on separate pages. A mechanism here is the canonical arrow pushing for a class, run on real structures and labelled rule-derived. It is not evidence, and this record is not a mechanism.
